When to plant daffodils in Macon: by 1 November

Daffodil in Macon: depth, winter cold, pests and pets

Plant daffodils three times the bulb’s height deep (RHS): about 13–15 cm for large bulbs, 15–20 cm apart (University of Georgia Extension). The RHS advises planting them early in autumn, ideally in September in the UK, so do not leave them late: aim for the start of the window, 1 November.

In Macon the average daily temperature stays at 10 °C or lower for about 4 weeks a year (our estimate from ten years of monthly weather). For this bulb Wisconsin Horticulture Extension gives a cold period of 15–17 weeks at about 2–10 °C. That is less than the bulbs need, and without more cold they may not flower properly. In hot, humid Georgia (US) many large daffodils flower well in the first year and few, if any, in the second; ‘Ice Follies’ and the small tazetta daffodil ‘Erlicheer’ have done well there (University of Georgia Extension). Paperwhite narcissus needs no cold period at all (Wisconsin Horticulture Extension).

Daffodils are long-lived: clumps slowly expand over the years (RHS). Leave the leaves for at least eight weeks after flowering — they feed next year’s flowers (University of Georgia Extension).

Squirrels avoid daffodils, so they can be planted among tulips to reduce losses (RHS). Daffodils are toxic to dogs, cats and horses; the bulbs are the most poisonous part, and a large amount can cause convulsions and heart rhythm problems (ASPCA).
